FUELIZER.

Application tiled January 15, 1921. Serial No. 487,539.

To all whom t may concern.'

Be it known that I, JOHN G. LANNING, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Fuelizers, of which thefollowing is a specification, reference being had therein to the accompanying drawings. l0 'The invention relates to fuelizers of that type in which a combustible mixture is burned and the' products of combustion introduced intp an engine intake to assist in the vaporization of the liquid fuel. It is the object of the invention to automatically control the quantity of heated products thus intro- Y duced according to the requirements ofthe engine and to thisend the invention consists: Afirst, in the construction for thermostatically controlling the operation of the uelizer;

and second, in various features of constructionv as hereinafter set forth.

In the drawings: Figure Vl is a cross-section through a fuelizer of my improved construction ;l

Figure 2 is a vertical longitudinal section therethrough;

Figure 3 is a horizontal longitudinal section; r

Figure 4 is a front elevation; V l Figure 5 is a section through thethermostat.

The uelizer to which my improvements are applied may be of any suitable-construcu tion, but as shown, A isa casing or fitting Y,

adapted to be--nserted between the carburetor and manifold 'of an internal combustion engine. B is a conduit section formed within said tting and forming a portion u ofthe intake. Cv is a jacket surrounding j this conduit section and vforming a combustion chamber, and D is a jacket surrounding the jacket C. At one side of the casing is an extension E forming an enlargement F l of the combustion chamber and connected to this extension is the spark plug G. At one point the chamber between the jacket C and `the conduit B is connected bya port H with the interior of the conduit B for the pur- 5 ose of introducing gases into the intake. I is a baille between the port H and the chamber F for .compelling the products of combustion to encircle the conduit B before passing through said port."

The combustible mixture isv referably obtained from the carburetor and is first introduced into the chamber between the jacket D and the jacket C. As shown, this is'accomphshed by a port J, which registers with a corresponding port K in the ange of the carburetor and connecting with the mixing chamber thereof. The combustible mixture, after passing through the port J encircles the jacket andinally passes into the chamber F Where ignition takes place, the flame and products of combustion assing around within the inner jacket and) the products passing through the port H into the intake. In thus passing around 'the inner jacket, heat is communicated to the walls thereof andl to the incoming mixture in the outer jacket, so that the fuel thereof is vaporized 'before introduction into the chamber F.

As has been stated, it is the object ofthe present invention to automatically control the quantity of the products of combustion entering the intake, which is accomplished through a thermostat. As shown, thisthermostat'L, which may be ofany suitable construction, is located adjacent to the port for connecting the outer and inner jackets and this port is controlled by a Valve M operated bythe thermostat. the port or ports N for connecting the outer and inner jackets are formed in a "cylinidrical member O, which is embraced by the `cylindrical valve M.

The thermostat L is affected by the heat communicated thereto from the casing. A, the arrangement being such that with increase of heat, the valve M is shifted to cut down the open area of the Specifically,

ports N, thereby diminishing the quantity p of combustible mixture which can pass from the outer jacket to the combustion chamber F. Thus when thev engine is first started and the parts are all cold, there will be a relatively large area of opening in the lports N, so that the amount of combustible mixture which is ignited by the spark plug G is correspondingly large. This will rapidly heat up the casing A, while the heated products of combustion will supply the requisite heat to the intake and as soon as properly" heated, the thermostat L will out down upon j the supply. 1n this Way the quantity of mixture burned is regulated automatically, according to the requirements of the engine.

As shown in Figures i and 5, the thermostat is in the form. of a. spiral P of composite metal, which will expand diierentially and causea rotation of one end of the spiral relative to the other. One end' 1s anchored to the cylinder O, being attached thereto by a clamping screw Q, while the other end is attachedto a sleeve M which constitutes the valve. This sleeve has a port R therein which normally registers with a series of ports N and upon the expansion of the spiral and rotation of the sleeve these ports will be gradually cut oil". There is also a single port N which is not controlled by the valve and which will furnish the -minimum amount of combustible mixture required. The whole construction is enclosed 'in a hollow cap S, which has a 'threaded engagement with the casing A.
